HAMMERHEAD KEY 230mm
£ 195.00 www.squirelocks.co.uk
The Hammerhead U-lock from British company Squire – who supplied locks to the Napoleonic War, would you believe – is available with key and combination lock systems. Sadly, it proved sticky and difficult to open after the corrosion tests. With so many of the locks tested showing similar results, this was disappointing, though it higlighted why you must protect your locking mechanism from the elements. The Squire’s bracket wasn’t up to much, either, lasting a few seconds before ejecting the lock. After that the results were much better: its crop resistance is good, and the same can be said for sawing, twisting and pulling, though it didn’t fare that well against our angle grinder.
